Product Details

These ISR Performance full subframe solid inserts fit the 1989-1994 Nissan 240SX RWD (S13).

ISR Performance Full Subframe Solid Inserts for the 1989-1994 Nissan 240SX (S13) are built to fill the squishy voids of factory rubber, tighten chassis response, and bring a focused, direct feel to the Nissan 240SX. If you've lowered the 240SX on coilovers or dropped springs, factory hardware in this location can no longer keep the alignment honest — these parts solve that problem and sharpen how the chassis feels under load.

Every ISR full subframe solid inserts set uses CNC-machined billet construction with performance-grade spherical bearings or poly bushings where appropriate. Bolt them in using OEM mounting points — no welding, no cutting — and get the S13 240SX back into alignment spec with the adjustment range daily-driven, canyon-carved, and track-day 240SX owners actually need.

Features

  • Fills voids in OE subframe bushings for near-solid mounting
  • Sharpens chassis response and eliminates rear axle deflection
  • Machined aluminum inserts, precision fit to factory bushings
  • Reversible installation if desired
